The nature of Fusarium wilt disease resistance in tomato

Creator:: Stromberg, Erik Leslie
Abstract:: Bioassays of acetone extracts from xylem tissue in tomato stems and corresponding reductions in Fusarium oxysporum f.sp. lycopersici race 1 or 2 populations within the stems suggest that fungitoxic materials within the xylem vessels of Bonny Best, Jefferson, and Marglobe tomato cultivars initially kill a portion of the inoculum conidia....

Copper tolerance in four fungal species

Creator:: Grable, Carl Ivan
Abstract:: This study was initiated to determine the tolerance to copper of Aspergillus niger, Stemphylium sarcinaeforme, Monilinia fructicola and Fusarium oxysporum f. sp. lycopersici. Included were strains of the latter two fungi that were induced to tolerate relatively high levels of copper by continual culture on sublethal levels of the toxicant....

Fluorescence studies on the bases of the nucleic acids in solution at room temperature

Creator:: Hauswirth, William Walter
Abstract:: Fluorescence of adenine, guanine, thymine, cytosine, and uracil has been detected at room temperature in neutral aqueous solution using a digital signal accumulation technique and right angle fluorescence detection from solutions with absorbances between 0. 4 and 0. 7. The quantum yields are respectively 2.6 x 10⁻⁴, 3.0 x 10⁻⁴,...

A study of the photolysis of the aqueous thymine system at 214 nm, 229 nm and 254 nm

Creator:: Satcher, Robert Lee
Abstract:: The photolysis of the aqueous thymine system has been investigated at 214 nm, 229 nm and 254 nm at room temperature. Products of photolysis have been identified as hydrogen peroxide, 6-hydroxy-5- hydroperoxy thymine and tentatively 5-hydroxy-6-hydroperoxy thymine. These together with thymine loss, were determined quantitatively under a variety of conditions....

The solid state photochemistry and photophysics of a triphenylmethyl dye cyanide

Creator:: Vernier, David L.
Abstract:: Triphenylmethyl dye cyanides have been known to be sensitive to ultraviolet radiation since early in this century. Under appropriate conditions, exposure to uv leads to heteropolar fission of the C-CN bond (photoionization) and intense coloration due to dye formation. Thin homogeneous films of hexahydroxyethyl pararosaniline cyanide in a nylon matrix...

Nucleoprotein structure of adenovirus

Creator:: Corden, Jeffry Lynn
Abstract:: The structure of the nucleoprotein core of adenovirus has been investigated. Using a combination of biophysical techniques and nuclease digestion I have determined that the adenovirus core, as isolated with pyridine, shares several physical properties with cellular chromatin. The most notable difference is the lack of a nucleosome repeat in...

Morphological and meristic characteristics of ten populations of blackside dace, Rhinichthys osculus nubilus (Girard ), from western Oregon

Creator:: Zirges, Malcolm H.
Abstract:: Blackside dace, Rhinichthys osculus nubilus (GIRARD), were collected from ten western Oregon streams and examined for variation among morphological and meristic characters. Several characters were observed to vary between populations studied. Number of vertebrae, number of scales in and above the lateral line, length of snout, and depth of body...
